you will need the proper (externally) balanced flywheel for the 400.a 350 is internally balanced and the flywheel will not work.

GO TO EBAY RIGHT NOW and type in a search for "400 block." I just did, checking prices on a bare block, and found for $26 I think the adapter to use any 263-350 sbc flywheel.
I think it ends in a day or so.

Here's the link:

Don't forget to check the block to make sure the clutch linkage stud boss is drilled and tapped. Many 400's were not and it's a pain to do in the car. The boss is above the oil filter mount.
